Need your "expert" opinion on my backlink strategy!

Hello,
I am currently working on a long tail keyword. I am in need of your valuable guidance regarding the strategy I want to apply. I haven't used it yet but wanted to use if it really gonna work!


I will explain my strategy and please let me know if it is anyway going to work for me!


1.I have done a research and found a "long tail" keyword which has exact 3000 monthly searches with medium competiotin.
2.Now by using google keyword tool I identified a set of 3 keywords related to my main keyword with nearly 2000+ exact searches globally per month and have "low" competition.
3.Now I registered a domain with exact longtail keyword and with dot "com" extension. Installed a wordpress platform.
4.Now I have created 15 posts related to my keyword with 500+ words in each and 100% unique with good quality. (Not top notch as I am not native english person)
5.Now to my main domain I manually created 20 web 2.0 blogs including wordpress, blogspot,tumbler, etc.
6.Now in each of these blogs, I posted 1 500+ blog post which contains href links to my main site with 3 keywords. All three keywords are placed in different paragraphs of the article and links to my main site.
7.Besides only one post in the blog, I have added links to my main site in side bar.


8.Now I am willing to take these 20 web 2.0 links and have a SeNuke blast on them. So basically these web 2.0 blogs will works as tier one for my campaign.
9.While having this blast I will use those 3 keywords only.


So my ultimate question is, "Do this strategy have some value?"
Can I expect some SERP movement or it's just a CRAP?
If it has some value, does it stick for long or it will be a "churn and burn" type?


If I am doing anything wrong at any place, please correct me. I am a bit new and would like to try my luck in internet marketing and SEO.


Thanks!

I need guidance on the strategy. Ultimately I will be finding my new way but to start with something, does my strategy looks anyway good?

How close is the domain to the actual search term? "long" domains aren't really welcome by Google that much these days. I've seen clients tank their strategies with domains over 12-15 characters.

First thing is you have to make sure your money site content is top notch. Grammar errors and bad spelling just won't fly.

Replace SENuke with GSA SER too.

For the 15 articles, dont make them all around the same keywords, no point trying to rank all the pages for the same keyword. Find some more longtails related to it, or write about anything related even if it doesn't rank, to fill up the site with content.
